I claim as my invention l. A gas burner of the character described, comprising a frusto conical burner-body containing a correspondingly-shaped mixing g chamber of uniform taper from end to end thereof and having an air inlet at its flared end and a mixture outlet at its converging front end, and a detachable bridge bar arranged transversely of the burner-body at the flared end of its mixing chamber and containing a threaded opening for connecting the body to a supply nipple, the front end of said opening terminating in an orifice for admitting gas to said mixing chamber.

20 2. A gas burner of the character described,

comprising a burner-body containing a forwardly-converging mixing chamber of a smooth uniform taper having an air inlet at its larger end and a mixture outlet at itsl a; smaller end, the larger end of said burnerbody having a pair of notches therein, and a detachable bridge-bar arranged transversely of the burner-body and having projections at its ends engaging said notches, said bar S0 being adapted for attachment to a gas pipe and containing an orifice for admitting gas to the mixing chamber.
